Problems solved by technology

[0005] However, sharing video slices on different cluster nodes will incur network transmission costs
In addition, the scheduling of the process itself also has a cost
Finally, this method can easily cause a large transcoding task to occupy all cluster resources, thus blocking the system
At this time, other tasks must be queued in the task queue. Even if it is a very short video, its own transcoding speed is very fast, and it needs to wait for a long time. Therefore, using this transcoding method, the actual waiting time still very long

Abstract

The invention discloses a self-adaptive high-performance video transcoding system and method. The self-adaptive high-performance video transcoding method comprises the following steps: S1, receiving a transcoding task, required by a video transcoding request system, through a dispatching core module, and selecting one node with the richest node resources in a transcoding processing module; S2, carrying out downloading and characteristic extraction on source files of a video by the transcoding processing module; S3, determining a transcoding type of the video according to a characteristic extraction result by the transcoding processing module; S4, carrying out the transcoding task on the video by the transcoding processing module, a transcoding node module and a transcoding combining module according to the transcoding type of the video; S5, sending the transcoded video to a video transcoding requiring system by the transcoding combining module, and sending transcoding finishing information to the dispatching core module. By adopting the self-adaptive high-performance video transcoding system and method disclosed by the invention, calculation resources can be utilized to the greatest extent and unnecessary queue waiting is avoided; the maximum transcoding speed and the shortest average transcoding time are realized.

Description

technical field [0001] The present invention relates to a video transcoding system and method, in particular to an adaptive high-performance video transcoding system and method, and belongs to the technical fields of high-performance distributed system architecture design and video encoding and decoding. Background technique [0002] Video transcoding is a key part of the video sharing process, and it is also the most time-consuming part. The length of time spent in transcoding directly determines the efficiency and experience of video sharing. In the prior art, there are two commonly used transcoding methods as follows: [0003] 1. The most traditional method is to complete all transcoding tasks of the entire video on a certain node of the cluster. This method cannot evenly and effectively use all the computing resources of the cluster. The transcoding speed is completely limited by the transcoding capability of a single node in the cluster. The transcoding speed is slow a...
